The effect of physical interventions on pain control after orthodontic treatment: A systematic review and network meta-analysis

En

by Junxiong Li, Siyu Li, Hongjun Chen, Jingzhe Feng, Ya Qiu, Lihua Li

Objective

Pain is a frequent adverse reaction during orthodontic treatment, which can significantly reduce treatment compliance and compromise the expected treatment effect. Physical interventions have been used to alleviate pain after orthodontic treatment, but their effectiveness is controversial. This study used a network meta-analysis to assess the efficacy of various physical interventions typically used in managing pain after orthodontic treatment... Читать дальше...

A biodynamic model predicting copper and cadmium bioaccumulation in caddisflies: Linkages between field studies and laboratory exposures

Plos.org 
En

by Michelle I. Hornberger

Hydropsyche and Arctopsyche are filter-feeding caddisflies (Order: Trichoptera; Family: Hydropsychidae) that are commonly used to monitor metal exposures in rivers. While tissue residue concentrations provide important bioaccumulation data regarding metal bioavailability, they do not provide information regarding the mechanisms of uptake and loss, or exposure history. This study examined the physiological processes that control Cu and Cd uptake and loss using a biokinetic bioaccumulation model. Читать дальше...

Empirical Bayes factors for common hypothesis tests

Plos.org 
En

by Frank Dudbridge

Bayes factors for composite hypotheses have difficulty in encoding vague prior knowledge, as improper priors cannot be used and objective priors may be subjectively unreasonable. To address these issues I revisit the posterior Bayes factor, in which the posterior distribution from the data at hand is re-used in the Bayes factor for the same data. I argue that this is biased when calibrated against proper Bayes factors, but propose adjustments to allow interpretation on the same scale. Читать дальше...

Tests of fit for the power function lognormal distribution

by Chao Wang, He Zhu

In this study, tests of fit for the power function lognormal distribution is considered. The probability plot, probability plot correlation coefficient, and goodness-of-fit tests—the Kolmogorov–Smirnov (KS), Cramér–von Mises (CvM), and Anderson–Darling (AD) tests are provided. Tables of critical values are presented by using simulation techniques, and the AD test outperforms KS and CvM tests based on power comparisons. Finally, to illustrate these test procedures, we...

Assessment of the stiffness of the upper trapezius muscle in a group of asymptomatic people with cervical spine rotation asymmetry

Plos.org 
En

by Michał Wendt, Małgorzata Waszak

This study investigated the relationship between the stiffness of the upper trapezius muscle and the range of rotational movement of the cervical spine. A total of 60 right-handed asymptomatic students participated in the study. Participants (N = 22) characterised by asymmetry in rotational movements were selected for the experimental group. A difference of ≥10° between right and left rotation of the cervical spine was considered asymmetrical. The control... Читать дальше...

Reshaping the narrative: Tracing the historical trajectory of HIV/AIDS, gay men, and public health in Sweden

Plos.org 
En

by Fredrik Nyman

The human immunodeficiency virus (HIV) emerged as an endemic health crisis in the United States during the early 1980s. Initially labelled a “gay disease” due to its prevalence among gay men, the spread of HIV led to widespread fear and moral panic, as there was limited medical knowledge on preventing its transmission. While HIV is often associated with Sub-Saharan Africa, this article focuses on Sweden, a pioneering nation that became the first to achieve the remarkable... Читать дальше...

Healthcare professionals’ perception and COVID-19 vaccination attitudes in North-Western Ghana: A multi-center analysis

Plos.org 
En

by Augustine Ngmenemandel Balegha, Suburu Abdul-Aziz, Louis Mornah

Introduction

The novel coronavirus SARS-CoV-2 causes Coronavirus Disease 2019 (COVID-19). Vaccination has been identified as one of the most effective strategies for combating COVID-19. Positive perceptions and attitudes of HCPs towards the COVID-19 vaccination are essential to vaccine uptake and adherence. However, the perceptions and attitudes of HCPs towards the COVID-19 vaccination remain largely unexplored. We therefore... Читать дальше...

Genetic changes and testing associated with childhood glaucoma: A systematic review

Plos.org 
En

by Anika Kumar, Ying Han, Julius T. Oatts

Many forms of childhood glaucoma have been associated with underlying genetic changes, and variants in many genes have been described. Currently, testing is variable as there are no widely accepted guidelines for testing. This systematic review aimed to summarize the literature describing genetic changes and testing practices in childhood glaucoma. This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic... Читать дальше...
